Detectives overseeing the new forensic searches of Claudia Lawrence's home four-and-a-half years after she vanished, say there is no "smoking gun" or breakthrough in the case. But for her family, the new review offers hope that the mystery of what happened to her may be solved.

Her parents, Peter and Joan Lawrence have been calling for a new investigation and met with North Yorkshire's new Chief Constable Dave Jones in recent weeks. Two earlier reviews of the case were carried out by the National Policing Improving Agency (NPIA) in 2009 and 2010.

Earlier this year, North Yorkshire Police said:"Their (the NPIA) report concluded that the investigation had been conducted with integrity and objectivity...and that, where individuals had been subject to investigation, no opportunities had been overlooked."
